Revisiting Atrioventricular Septal Defects: Exploring Chromosomal Abnormalities, Cardiac and Extracardiac Anomalies in a Contemporary Prenatal Cohort.

To estimate if there is an association between partial AVSD with chromosomal abnormalities, cardiac and extracardiac malformations, and to report the outcomes of prenatally diagnosed AVSD in a large, contemporary cohort. This is a retrospective cohort study of 190 prenatally diagnosed fetal AVSD between 2014 and 2023. Type of AVSD (complete vs partial), additional cardiac findings, extracardiac findings, presence of a heterotaxy, results of prenatal karyotype, and pregnancy outcomes were documented and analyzed. A total of 190 cases of fetal AVSD were analyzed. Complete AVSDs comprised 141 (74.2%) of the cohort, while partial AVSDs comprised 49 (25.7%). Karyotype was completed in 131 cases, and in 98 (74.8%) cases chromosomal abnormalities were identified, with trisomy 21 being the most common (53/131, 40.5%). Complete AVSDs were associated with trisomy 21 (45.5%, p = 0.04), Isolated cases of complete AVSDs (p = 0.03). Partial AVSDs were associated with trisomy 18 (53.1%, p < 0.001). In cases of partial AVSDs with aneuploidies, 7 (70%) had an ostium primum defect and 20 (90.9%) of AV canal type VSD. Isolated partial AVSD had no clear association with aneuploidies. There were additional cardiac anomalies in 96 (50.5%) and extracardiac anomalies in 134 (70.5%) of the cohort. There were no differences between partial and complete AVSD in rate of additional cardiac and extracardiac anomalies. AVSD was part of a heterotaxy in 47 (24.7%) of cases, and heterotaxy was associated with complete AVSD in the majority of cases (43/47, 91.4%, p = 0.003). Fetal partial AVSDs are associated with trisomy 18. Fetal complete AVSDs, even isolated, are associated with trisomy 21. There were no differences in association of other aneuploidies, additional cardiac findings, or extracardiac anomalies between prenatally diagnosed complete AVSDs and partial AVSDs.

Navigating the spectrum of double-outlet right ventricle presentations: Outcomes from a contemporary cohort based on subtypes.

PURPOSE: Our aim in this study was to investigate the prenatal and postnatal prognosis of double outlet right ventricle (DORV) cases diagnosed prenatally by analyzing the outcomes based on the subtype. METHODS: This study is a retrospective chart review. Cases diagnosed with fetal DORV by prenatal ultrasound in the maternal-fetal medicine department of our hospital between 2014 and 2022 were included. Data on maternal characteristics, fetal echocardiographic features (type of DORV), pregnancy and neonatal outcomes (termination of pregnancy [TOP], intrauterine fetal death [IUD], neonatal death [NND], death in infancy (IND), survival) were collected and analyzed. RESULTS: Ninety-nine cases of prenatally diagnosed cases of DORV were included. The prenatal diagnosis was right in 97% of the liveborn fetuses. The cases were classified into subtypes, including transposition of great arteries (TGA), Fallot, ventricular septal defect (VSD), remote, and heterotaxy types. The cohort consisted of 32.3% TGA type, 19.1% fallot type, 11.1% VSD type, 2% remote type, and 35.3% heterotaxy type of DORV. An additional cardiac anomaly was observed in 87% and an extra-cardiac anomaly was observed in 54% of the cases. When we excluded the cases with heterotaxy type but without any chromosomal abnormality, additional genetic abnormalities were detected in 42% of the remaining cases. Outcome of pregnancy was livebirth in 68/99 (68.7%), IUFD in 5/99 (5.1%), and TOP in 26/99 (26.3%). Postnatal cardiac surgical repair was performed in 48 cases. Survival among livebirths was 39/68 (57.3%). Twenty-nine neonates or infants who had additional cardiac anomalies and/or genetic abnormalities died before any surgical intervention. The postoperative survival rate was 39/48 (81.2%). CONCLUSION: The prognosis in DORV depends on the anatomical subtype, the presence, and severity of associated anomalies. Survival increases in isolated cases without any additional structural or genetic anomalies.

Prenatal diagnosis of right aortic arch: associated anomalies and fetal prognosis according to different subtypes.

OBJECTIVES: Right aortic arch (RAA) is a rare anomaly with an incidence of 0.1 % in the adult population and low-risk fetuses. Our aim in this study was to evaluate associated anomalies and conditions according to subtypes. METHODS: This was a retrospective study examining consecutive pregnancies diagnosed with RAA in our hospital between 2018 and 2022. Fetuses with RAA were divided into three groups, RAA with right-sided ductus arteriosus (RAA-RDA), RAA with left-sided ductus arteriosus (RAA-LDA), and RAA with a double aortic arch (RAA-DAA). RESULTS: A total of 81 fetuses were diagnosed as having RAA during the study period. The rate of cardiac anomalies (82.8 %) in the RAA-RDA group was higher than in the RAA-LDA (17.6 %) and RAA-DAA (22.2 %) groups (p<0.001). No statistically significant difference was found between the groups in terms of maternal age, diagnosis week, pregnancy outcome, extracardiac anomalies, and genetic anomalies. Three (8 %) of 36 fetuses with isolated RAA who resulted in live birth developed symptoms related to the vascular ring, and one (2.7 %) newborn with RAA-DAA underwent surgery. CONCLUSIONS: The incidence of cardiac anomalies is high in fetuses with RAA-RDA. Ultrasound examinations should be performed for cardiac anomalies and additional structural anomalies. Vascular ring formation is a rare but important complication due to compression risk to the trachea and esophagus.

Persistant Left Superior Vena Cava with and Without Right Superior Vena Cava: Significance of Prenatal Diagnosis.

This study aims to define the associated anomalies with PLSVC, and to compare single PLSVC and bilateral superior vena cava in terms of accompanying anomalies and pregnancy outcomes. This was a retrospective study of the fetuses diagnosed with single and/or bilateral SVC at a tertiary fetal medicine center during 8 years. We detected 16 cases of single PLSVC and 84 cases of bilateral SVC. We found an association between the PLSVC and cardiac and extracardiac anomalies. Comparison between single PLSVC and BSVC cases revealed significant differences in the occurrence of heterotaxy and right isomerism. The study highlights the importance of prenatal diagnosis in PLSVC cases. Isolated PLSVC with situs solitus may be considered a benign finding, but larger studies are needed to understand the clinical implications of PLSVC in relation to chromosomal anomalies. Routine screening protocols should include three-vessel and trachea views to detect PLSVC.

Pulmonary atresia and ventricular septal defect: How accurate is the fetal echocardiography, and do the major aortopulmonary collateral arteries matter?

OBJECTIVE: To assess the accuracy of prenatal echocardiography in defining pulmonary vasculature in pulmonary atresia with VSD (PAVSD). The second aim is to compare the perinatal and postnatal outcomes of different pulmonary blood supply types. STUDY DESIGN: The cases prenatally diagnosed with PAVSD between 2017 and 2022 in a single tertiary fetal medicine center were identified on the electronic database. Fetal echocardiography reports and images were reviewed retrospectively. Postnatal outcomes were acquired from the hospital records of relevant pediatric cardiology and cardiovascular surgery clinics. Fetal echocardiography results were compared with postnatal results. Perinatal and postnatal outcomes were compared between the different pulmonary vascular supply types. RESULTS: Among the 24 PAVSD cases, six were diagnosed with major aortopulmonary collateral arteries (MAPCA) dependent, eleven were diagnosed with ductus arteriosus (DA) dependent pulmonary supply, and seven were diagnosed with double pulmonary supply (MAPCA + DA) on prenatal echocardiography. Seventeen cases were live-born and have undergone postnatal investigations. Fetal echocardiography was 88.2% accurate about the type of pulmonary supply. The accuracy of fetal echocardiography regarding pulmonary vascular anatomy was 82.3%. Postoperative survival was 69.2%. Mortality before surgery and postoperative survival did not differ between pulmonary supply groups. Survival was impaired by the extracardiac anomalies. The need for early interventions was significantly higher in the DA group. CONCLUSION: Pulmonary vascularization in PAVSD can be defined precisely on fetal echocardiography. The source of pulmonary blood supply does not impact postnatal short-term outcomes significantly but it impacts the management. The associated anomalies highly contribute to postnatal mortality.

Assessment of fetal myocardial performance index in pregnant women with SARS-CoV-2 infection: A prospective cohort study.

OBJECTIVES: Our aim was to investigate the effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on fetal myocardial performance in women who had it during their pregnancy. MATERIALS AND METHODS: In our prospective cohort study including healthy pregnant women and pregnant with SARS-CoV-2 infection, we collected patients' data between June 2021 and April 2022. Maternal characteristics, gestational age at SARS-CoV-2 infection and ultrasound examination, and body mass index were noted. Fetal biometry, fetal anatomy scanning, placenta, amniotic fluid index (AFI), and Doppler parameters were routinely examined in all patients. Left ventricular myocardial performance index (MPI) was measured during fetal echocardiography examination. Doppler parameters, AFI, and MPI values were compared between two groups. RESULTS: Compared with the control group (n = 80), MPI values were found within normal limits in fetuses of pregnant women with SARS-CoV-2 infection (n = 80) (MPI: 0.38 ± 0.06 in the control groups vs. 0.39 ± 0.05 in the SARS-COV-2 positive group, p = 0.79). There was no relationship between SARS-CoV-2 infection and changes in AFI and umbilical artery pulsatility index (PI) values. Uterine artery PI values were significantly higher in pregnant women with (SARS-CoV-2) infection (0.81 in the control group vs. 0.97 in the SARS-CoV-2 group, p < 0.05). CONCLUSIONS: Fetal cardiac functions were not affected in pregnant women with previous (SARS-CoV-2) infection. Further metaanalyses are warranted to confirm the results.

Clinical and genetic aspects of termination of pregnancy; tertiary center experience.

Objective: The aim of the study was to retrospectively analyze the indications Techniques and complications of pregnancy termination performed in a tertiary center. Materials and Methods: All cases between 10 and 33 weeks of gestation between January 2021 and June 2023 were retrospectively analyzed. The patients were divided into two groups as group 1 with 11+0 to 21+6 gestational weeks and group 2 for those at 22+0 and 33+0 gestational weeks. Results: A total of 568 pregnancy terminations were included in the study. Among all terminations the most common fetal indications were central nervous system anomalies (148 cases, 26%) and trisomy 21 (53 cases, 9%) and the most common maternal/obstetrical Indication was previable premature rupture of the membranes (179 cases, 31.5%). Abnormal genetic results were found in 50 of 173 cases (28.9%) with a termination indication of Structural malformation who accepted invaziv genetic testing. The number of terminations with fetal indications performed after 22 weeks were 148 (41%) and 11 (7.4%) cases of these late terminations of pregnancy were anomalies expected to be diagnosed in the first trimester. Complication rates (12.4%) and abdominal termination rates (3.5%) were significantly higher in group 2 than in group 1 (p<0.05). Conclusion: Improvements in prenatal genetic screening and diagnostic techniques will undoubtedly decrease the gestational ages in terminations of pregnancies. However, there will always be cases that can neither be diagnosed earlier nor can be treated due to the nature of the anomaly. In the management of such cases, terminations will always occupy an important place in prenatal care.

What to expect after birth in idiopathic polyhydramnios? An analysis of postnatal diagnoses and their relationship to the polyhydramnios degree.

PURPOSE: To analyze postnatal abnormalities in idiopathic polyhydramnios and to estimate whether there was an association between the severity of polyhydramnios and postnatally diagnosed abnormalities. METHODS: This was a retrospective cohort study of all idiopathic polyhydramnios cases delivered at our center between 2017 and 2021. Cases were identified as idiopathic after excluding known fetal genetic or structural abnormalities (including soft markers for aneuploidies), Rh isoimmunization, fetal anemia, multifetal pregnancies, pregestational or gestational diabetes, and known infection with TORCH group agents. The primary outcome was the association between polyhydramnios degree and any abnormalities detected after birth. Additional outcomes were the odds of specific groups of abnormalities based on polyhydramnios degree. RESULTS: The prevalence of idiopathic polyhydramnios was 14.7%. Outcomes of 242 pregnancies with idiopathic polyhydramnios were analyzed. At least one neurodevelopmental, structural, or genetic abnormality was diagnosed in 16.1% of children born to women with idiopathic polyhydramnios. Moderate and severe polyhydramnios are significantly associated with at least one abnormality diagnosed after birth (45.9%, and 41.6%, respectively, p < 0.05). Neurodevelopmental disorders were the most frequent abnormality (5.4%), followed by genetic abnormalities (4.1%) and gastrointestinal abnormalities (2%). Odds of genetic abnormalities and neurodevelopmental disorders in moderate polyhydramnios were significantly higher compared to mild [OR 2.6; 95% CI 1.1-4.3 and aOR 2.4 (95% CI 1.1-3.6) respectively]. As expected, gastrointestinal anomalies were significantly associated with severe polyhydramnios [OR 3.2 (95% CI 1.9-5.5)]. CONCLUSION: Moderate and severe idiopathic polyhydramnios are associated with anomalies diagnosed after birth. Particularly high risks include neurodevelopmental disorders, genetic abnormalities, and gastrointestinal atresias.

An analysis of factors affecting survival in prenatally diagnosed omphalocele.

OBJECTIVES: To estimate factors affecting survival in prenatally diagnosed omphalocele, factors predicting genetic abnormalities, and association of omphalocele and specific groups of anomalies. METHODS: A retrospective observational study was performed, analyzing data of all omphalocele cases diagnosed prenatally in the perinatology clinic of a referral center. Demographic data, characteristics of the omphalocele (size, content, associated anomalies), results of genetic testing, pregnancy outcomes and postnatal outcomes were analyzed. RESULTS: Sixty-nine fetuses with omphalocele were included. The prevalence of omphalocele in livebirth was 0.007 %. Overall survival during the study period was 73.9 %. Twenty-eight (71.7 %) out of 39 cases with associated anomalies who were born live, survived, whereas survival was 85.7 % in the isolated cases. The most common anomaly associated with omphalocele were cardiac defects with 42 %; followed by placental or umbilical cord anomalies (28.9 %), skeletal defects (27.5), genitourinary anomalies (20.2 %), central nervous system (18.8 %) and facial anomalies (7.2 %), respectively. Eighty-five percent of the fetuses had at least one additional anomaly or ultrasound finding. Skeletal abnormalities and staged surgical repair of omphalocele were associated with survival. Associated skeletal anomalies and staged repair significantly increase the risk of postnatal death (OR: 4.6 95 % CI (1.1-19.5) and (OR: 10.3 95 % CI (1.6-63.9), respectively). CONCLUSIONS: Associated skeletal abnormalities and staged surgical repair are negatively associated with postnatal survival.

Comparison of oxidative stress markers in the saliva, gingival crevicular fluid, and serum samples of pregnant women with gestational diabetes and healthy pregnant women.

BACKGROUND AND OBJECTIVE: To compare oxidative stress (OS) markers in the saliva, gingival crevicular fluid (GCF), and serum samples of pregnant women with gestational diabetes (GDM) and healthy pregnant women and to investigate the association between periodontal health/diseases and OS and GDM. METHOD: Eighty women with GDM and 80 healthy pregnant women were included in the study. Medical and clinical anamnesis was obtained from all the pregnant women included in the study, and their plaque index (PI), gingival index (GI), bleeding on probing (BoP), probing pocket depth (PPD), and clinical attachment level (CAL) measurements were performed. GCF, saliva, and serum samples were collected for the measurements of the local and systemic total antioxidant status (TAS) and total oxidant status (TOS). RESULTS: Clinical periodontal parameters were found to be significantly higher in the GDM group compared to the control group. The serum and saliva TAS, TOS, and TAS/TOS values were significantly lower in the GDM group than in the control group. In the analysis of the GCF samples, the mean TAS and TAS/TOS values were significantly lower and the TOS value was significantly higher in the GDM group than in the control group. The multivariate reduced model indicated that gravidity, salivary TAS/TOS, and GCF TAS were significant independent variables in the development of GDM (p < .05). CONCLUSION: Our results indicated that the OS of serum, saliva, and GCF samples increased in patients with GDM compared to healthy pregnant women. The role of local OS parameters in GDM may be associated with elevated clinical periodontal parameters.

Can we predict the need for postnatal surgery in patients with prenatal fetal lung masses detected by CVR value?

AIM: The purpose of this study is to evaluate whether CPAM-volume ratio (CVR) can predict postnatal management (follow up for resolution and surgical treatment) in fetuses with fetal lung masses in the prenatal period. MATERIALS AND METHODS: 44 patients who presented at our center with prenatally diagnosed CPAM (Congenital Pulmonary Airway Malformation) and BPS (Bronchopulmonary Sequestration) were analyzed. Obstetric history and outcomes, karyotype results, CVR, additional sonographic findings, characteristics of masses were recorded. CVR was calculated for all cases. In the study we sought to identify a CVR threshold and did not use the thresholds classically used in the literature. RESULTS: 20 fetal BPS and 24 CPAM cases were analyzed. After excluding 5 patients, 46% of the patients were diagnosed with BPS and 54% with CPAM. In this study the cut off < 0,53 for CVR is taken, it predicts the no need for postnatal surgery with a sensitivity of 85% and a specificity of 88%. When we take the > 0,76 cut-off value for patients who will require emergency surgery within the first 10 days, it predicts the need for surgery with 90% sensitivity and 89% specificity. In addition, it was determined that all patients with mediastinal shift were operated. CONCLUSION: We believe that the CVR value and the presence of mediastinal shift should be evaluated in all cases of CPAM and BPS for prediction of the surgery. Proper counseling about the prognosis could be given to the family in cases with mediastinal shift and CVR value above 0,76.

Fetal hydrometrocolpos: Challenges of prenatal differential diagnosis on ultrasound.

Hydrometrocolpos is a pelvic cystic mass representing the distension of the vagina and uterus due to a lower genital tract obstruction causing accumulation of utero-cervical-vaginal secretions or urine in the vagina and endometrial cavity. Prenatal diagnosis is uncommon and differential diagnosis of the underlying etiologies is quite challenging in the prenatal period. We present three cases of female fetuses with hydrometrocolpos and discuss the prenatal differential diagnoses in the light of ultrasound findings along with postnatal diagnoses and outcomes.

Contribution of chromosomal microarray analysis and next-generation sequencing to genetic diagnosis in fetuses with normal karyotype.

AIM: The aim of this study was to investigate the contribution of chromosomal microarray analysis (CMA) and next-generation sequencing (NGS) to genetic diagnosis in fetuses with normal karyotype who underwent invasive testing for different indications. METHODS: The results of invasive genetic testing performed at a tertiary center between September 2020 and March 2022 were retrospectively analyzed. Indications for invasive tests were classified as fetal structural malformation, presence of soft markers, and high risk in screening tests. CMA results were classified as pathogenic or likely pathogenic (pCNVs), benign (bCNVs), and variants of unknown clinical significance (VOUS). RESULTS: A total of 830 invasive tests were performed and aneuploidy was detected in 11.2% of the fetuses. CMA was performed in 465 fetuses with normal karyotype, and pCNVs were detected in 6.9%. pCNVs were detected in 8.2% of fetuses with structural malformations, 6.5% in soft markers, and 4.7% in high risk in screening tests. Pathogenic variants were detected by NGS in 33.8% of fetuses with bCNVs. CONCLUSIONS: pCNVs can be significantly detected not only in fetuses with structural malformations, but also in invasive testing with other indications. NGS significantly contributes to genetic diagnosis in fetuses with structural malformations.

Prenatally diagnosed fetal thoraco-lumbar spine duplication associated with lipomyelomeningocele: An extremely rare case of split cord malformation.

Spine duplication is considered rare, a more serious form of split cord malformation. Ultrasonographic evaluation of the spine in the second trimester is central to the antenatal diagnosis of spinal malformations. Here, we report a case of thoraco-lumbar spine duplication associated with lipomyelomeningocele diagnosed by ultrasonography at 19 weeks of gestation. To the best of our knowledge, this is the first case report of spine duplication diagnosed by antenatal ultrasonography.

Intraamniotic digoxin administration versus intracardiac or funic potassium chloride administration to induce foetal demise before termination of pregnancy: a prospective study.

Different foeticide techniques and pharmacological agents have been used to achieve foetal asystole. This study aimed to compare the success of intraamniotic digoxin, intracardiac potassium chloride (KCl), and funic KCl in achieving foetal asystole and discuss procedural difficulties for physicians and clinical outcomes. This prospective observational study included 124 patients who received foeticide at 22-31 weeks of gestation. All procedures were performed transabdominally, and 1 mg of intraamniotic digoxin, funic KCl, or intracardiac KCl was administered. Procedure times, procedural difficulty scores, patient pain scores, decrease in haematocrit levels, induction and hospitalisation times, and the presence of chorioamnionitis were recorded. The foeticide success rates were 93.0, 95.1, and 97.5% for intraamniotic digoxin, intracardiac KCl, and funic KCl, respectively. Intraamniotic digoxin was associated with shorter procedure times, lower procedural difficulty scores, and lower patient pain scores (p < 0.001). Decreases in haematocrit, induction times, and chorioamnionitis were similar in all three procedures. Success rates and clinical results were similar for all three procedures. Foeticide with intra-amniotic digoxin has a high success rate, the procedure is easier to perform, and patients experience less procedural pain.IMPACT STATEMENTWhat is already known on this subject? Different foeticide techniques and pharmacological agents have been used to achieve foetal asystole. Pharmacological agents used in the foeticide procedure can be injected as intracardiac, funic, intrafetal, or intraamniotic, and the most commonly used are potassium chloride (KCl), digoxin, and lidocaine.What do the results of this study add? The success rates and clinical outcomes in achieving foetal asystole are similar for intracardiac KCl, funic KCl, and intra-amniotic digoxin procedures. Foeticide with intra-amniotic digoxin is less difficult to perform, and patients experience less pain associated with the procedure. All three techniques appear to be safe and have similar short-term obstetric outcomes.What are the implications of these findings for clinical practice and/or further research? Physicians may prefer foeticide with intra-amniotic digoxin as the procedure is technically simpler and has similar success rates to intracardiac or funic KCl administration. A prospective randomised study could better compare the advantages and limitations of the foeticide techniques.

Aspartate aminotransferase to platelet ratio index (APRI) score: is it useful in patients with intrahepatic cholestasis of pregnancy?

OBJECTIVE: It is aimed to evaluate the efficacy of using aspartate aminotransferase (AST)/platelet count ratio [AST to platelet ratio index (APRI) score] in ICP patients. METHODS: This study was carried out including 101 patients diagnosed with ICP (72 patients with mild ICP and 29 patients with severe ICP). Laboratory tests and neonatal outcomes of both groups were analyzed retrospectively. APRI scores were compared between the two groups. Receiver operating characteristic (ROC) analysis was used to evaluate the performance of the APRI score in determining the severity of ICP and the prediction of adverse neonatal outcomes. p < .05 was considered to be a statistically significant result. RESULTS: Patients with severe ICP had higher APRI scores than patients with mild ICP (p < .001). The cutoff value for the APRI score was 1.06, with 82% sensitivity and 72% specificity. There was also a significant positive association between APRI score and fasting bile acid level (r = 0.445, p < .001). In addition, elevated APRI scores were associated with meconium-stained amniotic fluid, neonatal intensive care unit admission and preterm delivery. CONCLUSION: The APRI score may not be the perfect differentiating method for the severity of ICP but it may help the clinician working with limited resources.

Does asymptomatic/uncomplicated SARS-CoV-2 infection during pregnancy increase the risk of spontaneous preterm birth?

OBJECTIVES: The aim of this study was to analyze the perinatal outcomes of asymptomatic/uncomplicated SARS-CoV-2 infection during pregnancy and the relationship between gestational age at the time of infection and spontaneous preterm birth (PTB). MATERIAL AND METHODS: This was a retrospective cohort study. The study population included pregnant women who were 19-45 years old and who had been admitted to a Research and Training Hospital for singleton birth delivery. Women who had contracted SARS-CoV-2 during their pregnancy (n = 102) were compared to those who were not infected (n = 378) for the development of spontaneous PTB and other perinatal outcomes. The factors associated with spontaneous PTB were analyzed through univariate and multivariate methods. RESULTS: Spontaneous PTB developed in 22.5% of the pregnant women with a history of SARS-CoV-2 infection and in 5.3% without a history of the infection (p < 0.001). The multivariate model determined that compared to the non-infected women, the OR of spontaneous PTB among those who had contracted the virus in the first, second, and the third trimesters were 9.13 (p < 0.001), 1.85 (p = 0.292) and 7.09 (p < 0.001), respectively. Pregnancy cholestasis (3.9% vs 0.5%; p = 0.020) and placental abruption (3.9% vs 0.5%; p = 0.040) were significantly higher in cases with a history of SARS-CoV-2 infection compared to the non-infected women. CONCLUSIONS: Asymptomatic or uncomplicated SARS-CoV-2 infection during pregnancy increases the risk of spontaneous PTB. This risk is higher particularly among pregnant women who develop the infection in the first and the third trimesters.

Positive effects of fetal echocardiography on maternal anxiety: a prospective study in a tertiary center in Turkey.

Aim: The aim of this study was to determine the anxiety levels of pregnant women who were referred to a tertiary center for fetal echocardiography (FE) and the effect of FE results on maternal anxiety.Methods: This prospective study was conducted between January 2020 and February 2021 and included 118 pregnant women. The anxiety levels of the participants were evaluated with the Spielberger State-Trait Anxiety Inventory, which evaluates state (STAI-I) and trait (STAI-II) anxiety. STAI-I and STAI-II were administered to participants at first admission using a standard interview technique prior to FE. After the FE was completed, a structured interview was performed and the state anxiety index (STAI-I-R) was re-administered to the participants.Results: Severe congenital heart disease (CHD) was detected in 63 (53.4%) fetuses. The participants' mean STAI-I scores were significantly higher than their mean STAI-II scores (44.19 ± 8.56 and 41.98 ± 5.98, respectively, t = 2.59 and p = 0.011). In pregnant women with fetuses with severe CHD, STAI-I-R scores were significantly lower compared to STAI-I scores (43.48 ± 7.97 and 46.28 ± 7.18, respectively, t = 2.13 and p = 0.037).Conclusion: Referral for FE is associated with increased maternal anxiety, and a structured interview may result in reduced anxiety levels even in those with abnormal FE.

Fetal Echocardiographic Findings to Predict Early Surgical Repair and Neonatal Outcomes in Fetuses with Isolated Coarctation of the Aorta.

OBJECTIVE: The aim of this study was to investigate fetal echocardiographic findings in predicting the need for surgical repair in fetuses with coarctation of the aorta (CoA) and to evaluate perinatal outcomes. STUDY DESIGN: In this retrospective study, fetuses diagnosed with CoA in a tertiary center between January 2015 and June 2021 were analyzed. Fetal echocardiographic measurements and quantitative findings, middle cerebral artery (MCA) and umbilical artery (UA) Doppler indices, and perinatal outcomes were recorded. RESULTS: A total of 57 fetuses with CoA were included in the study. In total, 51 (89.5%) pregnancies resulted in live births and 32 (62.8%) of the neonates underwent surgical repair. The left ventricle/right ventricle width ratio and aortic isthmus z-score were significantly lower in fetuses who underwent surgical repair (p = 0.004 0.001, respectively). Retrograde flow in the aortic isthmus (odds ratio [OR]:7.43; 95% confidence interval [CI]: 1.98-27.76), left-to-right foramen ovale shunt (OR: 8.50; 95% CI: 1.68-42.98), and ventricular septal defect (OR: 9.63; 95% CI: 1.90-48.74) were associated with the need for surgical repair. A new scoring system integrating these echocardiographic findings had 89% specificity and 54% sensitivity in predicting surgical repair. Fetal growth restriction rates, preterm birth rates, mean MCA pulsatility index (PI), and mean UA PI were similar in fetuses with and without surgical repair. CONCLUSION: A scoring system integrating echocardiographic findings in fetuses with CoA may improve the prediction of surgical repair need. There is no evidence of an increased risk of FGR, preterm birth, and brain sparing effect in fetuses with CoA who require surgical repair. KEY POINTS: · Coarctation of the aorta is one of the most difficult congenital heart defects to diagnose.. · A new scoring system may improve the prediction of surgical repair need.. · There is no increased risk of fetal growth restriction in fetuses requiring early surgical repair..

Preeclampsia: state of art and future perspectives. A special focus on possible preventions.

Preeclampsia (PE) is characterised by the new onset of hypertension after the 20th week of pregnancy, with or without proteinuria or hypertension that leads to end-organ dysfunction. Since the only definitive treatment is delivery, PE still represents one of the leading causes of preterm birth and perinatal mobility and mortality. Therefore, any strategies that aim to reduce adverse outcomes are based on early primary prevention, prenatal surveillance and prophylactic interventions. In the last decade, intense research has been focussed on the study of predictive models in order to identify women at higher risk accurately. To date, the most effective screening model is based on the combination of anamnestic, demographic, biophysical and maternal biochemical factors. In this review, we provide a detailed discussion about the current and future perspectives in the field of PE. We will examine pathogenesis, risk factors and clinical features. Moreover, recent developments in screening and prevention strategies, novel therapies and healthcare management strategies will be discussed.
